P. DEMEURE AND A. MAURITZ, OF NEW YORK, N. Y.

BED-BOTTOM.

Specification of Letters Patent No. 10,010, dated September 13, 1853.

T0 al w/wm t may concern Be it known that we, PIERRE DEMEURE and AUGUSTE MAUInTZ, of the city, county, and State of New York, have invented a certain new and useful Improvement in Bed-Bottoms; and we do hereby declare that the following is a full, clear, and eXact description of the same, reference being made to the annexed drawing, making a part of this specification, which is an isometrical view of our invention. Our invention consists in an improved construction of spring bed bottoms and bedsteads in combination therewith.

The improvement in the spring bottom consists in giving elasticity transversely in combination with the vertical action of the spiral springs. In the old spring mattresses this quality is wanting and the consequence is that a person lying upon one side of such a mattress will feel a tendency to roll o; the whole surface inclining toward that edge, for the straps which lace the springs together being rigid, cant. over or incline to one side such of the springs as are not being laid upon. In our improvement this is all avoided as the elasticity of the lateral or connecting wires so entirely prevents this that a person lying upon any part of the bed will only7 compress the springs directly under him and will be supported equally on all sides.

At A A is the frame of the bed-bottom which I prefer to have of metal.

B are a series of cross bars for supporting the spiral springs C of the ordinary construction.

Level with the frame A a series of long spiral springs are secured so as to form a net work as seen at D. The vertical spiral spring C stand in the square spaces formed by the net and are secured to these by four straps or links from opposite sides as seen at the letter (e). It is evident that the elasticity of the netting will enable those vertical springs to act to support a person, which are immediately under him and at his sides, allowing said springs to rise up on both sides alike, even though he may be near the edge, and secondly there will be vsuiiicient spring however near the edge to insure comfort in sleeping which is not the case upon the old mattresses having a rigid webbing at the top. To combine a folding bedstead with these springs: F and IW are the head and foot boards; these are hinged to the ends of the frame A so as to be capable of folding down upon the springs and when set up to open no wider than proper. A framing to which the legs are attached is hinged also to A as seen at Gr; the leg Gr heilig nearly at right angles to G. A brace bar I-I extends from where G joins the legs to the lower rail of the bed bottom A. This keeps the legs in their vertical position andsupports the bed.

By uncoupling the bolt H the legs will fold under and lie parallel with the rail A. Thus the bedstead can be transported wit-h the mattress without increasing the space occupied by the latter.

What we claim as our invention and desire to secure by Letters Patent is- The manner of constructing the spring mattress by combining the vertical springs with an elastic or spring net-work of spiral metallic springs for supporting said vertical springs, or for increasing the elasticity so that a person lying upon the bed will be equally supported on all sides as described.
